1. A bicycle sprocket having a rotational center axis, the bicycle sprocket comprising:
- a first tooth having a first axial chain engaging width that is smaller than a first axial spacing of an outer link and larger than a second axial spacing of an inner link coupled to the outer link, anda second tooth having a second axial chain engaging width that is smaller than the second axial spacing, the second tooth being formed by deformation of a material constituting the second tooth.

Abstract
A bicycle sprocket has a rotational center axis, and basically includes a first tooth and a second tooth. The first tooth has a first axial chain engaging width. A first axial chain engaging width is smaller than a first axial spacing of the outer link. Further, the first axial chain engaging width is larger than a second axial spacing of an inner link coupled to an outer link. The second tooth has a second axial chain engaging width. The second axial chain engaging width is smaller than the second axial spacing. The second tooth is formed by deformation of the material.
